A high pressure tank apparatus includes a high pressure tank, a leaked fluid container, and a supply/discharge side discharge flow path. The high pressure tank includes a liner made of resin, a reinforced layer that covers an outer surface of the liner, an insertion member that has formed therein a supply/discharge hole capable of communicating with an inside of the liner and the supply/discharge flow path; and a supply/discharge side cap in which are formed an insertion hole through which the insertion member is inserted and a supply/discharge side draw-out hole that draws out the fluid interposed between the liner and the reinforced layer. The supply/discharge side discharge flow path guides a temporarily released fluid that is the fluid drawn out via the supply/discharge side draw-out hole to a discharge region.

A fuel cell vehicle includes a travel prohibition control unit. In the case where a lid sensor detects an open state of a lid, the travel prohibition control unit performs travel prohibition control to prohibit travel of the fuel cell vehicle. In the case where the number of shift control operations has reached a release number within release time, the travel prohibition control unit releases the travel prohibition control, and in the case where the number of shift control operations has not reached the release number within the release time, the travel prohibition control unit continues the travel prohibition control. The release number is two or more.

A vehicle comprises a tank that is placed behind a front component in a front-rear direction of the vehicle and that is arranged such that a longitudinal direction of the tank is along the front-rear direction; and a fixation member configured to fix the tank to a vehicle body of the vehicle. The front component and the tank are arranged to at least partly overlap with each other when the vehicle is viewed from a forward direction side. The fixation member releases fixation of the tank to the vehicle body when the front component comes into contact with the tank to apply an external force along the longitudinal direction that is equal to or greater than a predetermined value, to the tank.

A vehicle understructure includes a hydrogen tank that is disposed along a longitudinal axis of a vehicle. At least an upper portion of the hydrogen tank is enclosed in a floor tunnel. The hydrogen tank includes dome portions that are disposed at both ends of a cylindrical center body portion of the tank, and at least one valve portion that protrudes from at least one of the dome portions. The vehicle understructure also includes a brace that extends along a transverse axis of the vehicle and is secured to transversely outer side portions of the floor tunnel. The brace is at least partially overlapped with at least one of the dome portions when viewed from the front or rear of the vehicle.

An fuel inlet port structure includes an inlet box having a box shape and having a box opening at its bottom, an inner panel disposed further inward of a vehicle with respect to the inlet box, and an inlet shield inserted through the box opening of the inlet box from outward of the vehicle and disposed between the inlet box and the inner panel. The inlet shield includes a barrel portion having a groove extending circumferentially along part of an entire circumference of an outer surface of the barrel portion at an outer edge.

A fuel cell system and a fuel consumption system verify the location of a filling failure at a time that a fuel gas filling process suffers from such a filling failure. Either one of encoded data indicating an infrared radiation signal related to the fuel gas filling process, which is sent from a vehicle to an external hydrogen station, and a drive signal, which comprises a train of binary pulses converted from the encoded data, is recorded in a recording unit of the vehicle.

A two-track multi-axle motor vehicle including at least two fuel tanks in which a fuel for producing driving energy for a vehicle drive unit can be stored under high pressure of the order of magnitude of 300 bar and more is provide. Each tank includes a safety valve device having a temperature-sensitive element monitoring only a partial region of the tank surface. The safety valve device allows at least a partial quantity of the stored fuel to escape from the respective tank at a higher temperature, which can occur, for example, in the case of a fire. The temperature-sensitive elements of at least two tanks are arranged here in such a manner that the distance between a left-side wheel (RL) of that vehicle axle, in the vicinity of which the at least two fuel tanks are arranged in the vehicle, and the temperature-sensitive element closest to the left-side wheel (RL) does not significantly differ from the distance of the other of the two temperature-sensitive elements from the right-side wheel (RR) of the vehicle axle.

A tool for draining and refilling a vehicle tank for cryogenic fuel, wherein the tool when in position for use has a vertical direction and includes a heat exchanger and a cooling tank, the cooling tank having an upper portion and a lower portion as viewed in the vertical direction of the tool and including a fuel outlet having at least one outlet valve, the fuel outlet being connected to a first fuel conduit and second fuel conduit via the at least one outlet valve, wherein the first fuel conduit includes an arrangement for connecting the first fuel conduit to an inlet on the heat exchanger, and wherein the second fuel conduit includes an arrangement for connecting the second fuel conduit to an inlet on a vehicle tank, the cooling tank further including an inlet, the inlet being connected to a fuel inlet conduit via a check valve and the fuel inlet conduit including an arrangement for connecting the inlet to an outlet from the heat exchanger, or to an outlet from a vehicle tank, and the outlet of the heat exchanger including an arrangement for connecting to an inlet on a vehicle tank, and a system and method for draining and refilling a vehicle tank.

An electric vehicle which can travel using a power generator that generates electric power based on hydrogen without increasing the size of the hydrogen tank, is provided. An electric vehicle includes a first tank configured to store an organic hydride, a dehydrogenation reactor that has a first passage including a first catalyst for accelerating dehydrogenation reaction of the organic hydride supplied from the first tank and separates the organic hydride supplied to the first passage into hydrogen and an aromatic compound, a power generator configured to generate electric power using hydrogen supplied from the dehydrogenation reactor, a power storage configured to store electric power generated by the power generator, and a motor drivable on electric power from at least one of the power generator and the power storage to rotate a wheel.

A high-pressure tank includes a liner for storing a fluid, and a reinforcing layer covering an outer surface of the liner and including a fiber wound around the liner and a resin. The reinforcing layer includes a helical layer group including laminated helical layers, and a large-angle layer provided adjacent to the helical layer group and on the liner-side. The helical layer group includes an innermost layer that is closest to the liner and that is one of first and second helical layers respectively having the largest and second largest fiber winding angles, an outermost layer that is closest to an outer surface of the high-pressure tank and that is the other one of the first and second helical layers, and an intermediate layer disposed between the innermost and outermost layers and including a helical layer that is smaller in winding angle than the innermost and outermost layers.
